Oscillations represented by curve 2 lags in phase by π / 2 and the periods are same. Amplitude of curve 2 is double that of 1 .

Q. The oscillations represented by curve 1 in the graph are expressed by equation $x = A sin ω t$ . The equation for the oscillations represented by curve 2 is expressed as:

$x = 2 A sin (ω t - π /2)$

$x = 2 A sin (ω t + π /2)$

$x = - 2 A sin (ω t - π /2)$

$x = A sin (ω t - π /2)$

Oscillations represented by curve $2$ lags in phase by $π /2$ and the periods are same. Amplitude of curve $2$ is double that of $1$ .

Q. The oscillations represented by curve 1 in the graph are expressed by equation x=Asinωt. The equation for the oscillations represented by curve 2 is expressed as:

x=2Asin(ωt−π/2)

x=2Asin(ωt+π/2)

x=−2Asin(ωt−π/2)

x=Asin(ωt−π/2)
